Tramadol (Ultram)

Tramadol is a centrally acting synthetic analgesic that appears to bind to opioid receptors to produce its narcotic-like effect. This drug is often used to relieve pain, especially after surgery. Like other pain killers, tramadol can become both physically and mentally addicting and should not be used for extended periods of time. Side effects include agitation, anxiety, convulsions, diarrhea, dizziness, and drowsiness.
